How to fix your headphones when they are wet?

Well unless you actually put them into the electric or music source afterdrying them, they should be working still, otherwise they're dead, or if you see any cuts in the wire, then the wire needs replacing or if you don't know how to do that I suggest buying a new pair

With any electrical equipment that has been subjected to any form of dampness NEVER attempt to connect it for use what you can try is thoroughly dry it with a hair dryer on medium heat be patient and take your time Then leave in a well heated ventilated place for a few days this may solve the problem for items which do not connect directly to the mains electricity

For Items that DO connect to mains electricity get professional help
